well, kind of. The XML is just being parsed by GRC to validate the input
of a field, color things etc.
However, there are only mappings in grc/python/Param.py for the
correctly wrappable python types.
You won't be able to have a let's say some Python class as param type in
GRC.

Yes, GRC isn't a complete language and doesn't implement things like it is. There are only a subset of possible data types. Using "gr_modtool add" to create a new block nicely gives you a lot of hints in the XML file it builds for you, including a list of all possible data types.

That is very clear.
Thank you very much.
